MAHLE PMU 400 contamination measuring system receives prestigious award

Stuttgart, 02. Februar 2022

  • MAHLE PMU 400 receives prestigious Prix de l’Équipement award from French magazine Décision Atelier
  • Precise counting of condensation particles convinces jury consisting of around 20 experts from automotive industry and trade
  • PMU 400 wins out against thirteen competing products from well-known manufacturers in Cleaning and Hygiene category 

MAHLE Aftermarket’s new PMU 400 contamination measuring system has been awarded the prestigious Prix de l’Équipementby French magazine Décision Atelier. Condensation particle counting, a sophisticated, high-tech process specifically chosen by MAHLE when designing the device, was the deciding factor for the jury consisting of around 20 experts from the automotive industry and trade. The PMU 400 beat out a total of thirteen competing products from well-known manufacturers in the Cleaning and Hygiene category.

The automotive supplier from Stuttgart developed the PMU 400 in response to the reintroduction of particle measurement at the tail pipe as part of the TÜV general inspection from 2023. Thanks to its condensation particle counting capability, the PMU 400 is also well equipped for future legislative changes involving stricter measurement tolerances and different engine types. In contrast to other measuring technologies on the market, this system can precisely measure the individual nanoparticles in the exhaust gas flow, particularly in gasoline engines and even at low concentrations. This means that the sample taken from the exhaust pipe can be attenuated with clean air by a factor of two hundred to minimize the deposition of particles and dirt in the most sensitive parts of the measuring device. The PMU 400 is therefore a highly reliable, low-maintenance measuring instrument with the additional benefit of intuitive operability. The PMU 400 is available as a stand-alone unit or as an add-on to the MAHLE EmissionPRO® and BRAIN BEE Emission Line equipment series.
